2 Acknowledgement and Word of appreciation In order to complete my career at the University of Utrecht as a student of the Master Business Informatics at the department of Information and Computer Sciences at Utrecht, I conducted this master thesis. After having only finished 7,5 out of the 10 courses, and not the BPM course itself, I was determined to do my master thesis on this particular subject. I was very determined to do so because the concept of BPM included many of the reasons why I wanted to start doing the master. Already I want to thank Pascal Ravesteyn and Hans Diepstraten for having faith in me conducting a master thesis with this lack of initial knowledge. Besides being very determined, I was also unsure of my own capabilities, mainly because I did not follow the BPM course yet. The latter however proved to be an advantage as certainly in the beginning I was almost unstoppable when reading scientific papers on the subject of BPM. This is one of the reasons I was able to complete the concept version of my thesis in 6 months. The second and foremost reason was the great quality help, quick responses and the everlasting flow of knowledge I received from all my supervisors and the colleagues at Creetion, in particular Pascal Ravesteyn, Hans Diepstraten, Peter de Bruin, Kees Terburg and Sander ten Hagen. I would also like to thank Johan Versendaal for giving me valuable feedback for completing my thesis by being the co reader and second supervisor. 2

3 Abstract Business Process Management (BPM) is one of those buzzwords which became an action on the agenda of today s organization. While multiple studies show people involved in BPM have different views on what BPM actually is, scientific literature agrees BPM is a holistic topic involving many different methods. BPM is being used as a way of managing all aspects of a business. Related IT implementations, such as ERP, show high failure rate. This is because it is not just an IT implementation but it also requires organizational change. Over the last 10 years many ERP implementations have been successful, but an equal amount, if not more, have been unsuccessful. The same can happen with the implementation of BPM if we not learn from the mistakes made with ERP implementations. Today several methods, tools and techniques are developed to guide an implementation of BPM and increase its chance of success. Examples are maturity models, implementation methods, success factors, roadmaps, delivery strategies, etcetera. Today s BPM maturity models rely heavily on the knowledge of the consultant using the model. Some models guide the consultants more than others, but it always comes down to the consultant identifying the opportunities for the organization. Consequently the usage of such models is limited because of the high level of required knowledge which can inhibit the usage of such a model. To address this problem an extensive literature study is done to determine what belongs within the scope of BPM, which studies are related and finally which opportunities can be identified for BPM. The exact topics covered in this thesis research are the history of BPM, Total Quality Management, Business Process Reengineering, Alignment and Maturity, BPM maturity models, BPM and Service Oriented Architecture, BPM suites, BPM and IT Governance, opportunities and finally BPM opportunities. The resulting framework was initially a BPM Opportunity Model and later an assessment method was added after the validation. While this model proved to have precious information for an organization to steer their BPM project or program with, its applicability was lacking because it is just a model. The concepts of a BPM opportunity, a BPM Opportunity model and the assessment method (developed to actually use the model) were evaluated and validated by means of multiple expert interviews, a knowledge sharing session, a questionnaire and four case studies. The first questionnaire revealed that there is a consensus on what the opportunities for BPM are between scientific researchers and professionals in the field. Out of the 73 opportunities identified 70 opportunities scored significantly high enough to be labeled as BPM opportunity. After four case studies, 52 opportunities formed a matrix which can be named as the BPM Opportunity model. The added value of this model in a practical real life case situation, is the identification of the current status of a BPM implementation. This status can be translated into opportunities that have not been exploited yet. By focusing on these particular opportunities a detailed report can be created presenting the complete opportunities including an elaborate description and best practice sources for these opportunities. 3

4 In the case of Stedin.net it was an acknowledgement of a feeling, confirming that the current BPM implementation halted at the operational level, and is now trying to push forward onto the tactical and ultimately (in many years according to the case study respondent) to the strategic level.

9 2 Methodology 2.1 Business Process Management and the Opportunities involved. Recently, more and more organizations start to invest significantly in Business Process Management (BPM) initiatives (Jesus 2009; Ravesteyn 2007; Weske 2004; Aalst 2003; Pritchard & Armistead 1999; Rudden, 2007). A study done by Gartner in 2004 reveals that of all IT investments an average of 43% in the subsequent years would involve Business Process Management(Woodley, 2005). Also in survey by Gartner, 53% voted for Continuous process improvement as the most expected benefit of BPM (Gartner, 2009). Benefits from BPM can be improved benchmarks, increased precision in measuring performance, increased overall operational efficiency and better knowledge about the internal and external processes. The benefits from these initiatives show it is not just a software project implementation, but also an organizational transformation. More and more BPM is being used as a way of managing all aspects of a business and a way of looking at the company regarding organizational effectiveness (Pritchard & Armistead 1999). Often a BPM implementation encompasses the implementation of a Business Process Management System (BPMS). When considering the implementation as a software development project, the business part of a BPM implementation is neglected. Both the IT and the management aspects should be covered (Ravesteyn 2009).This means when one wants to properly implement BPM, current software implementation methods and frameworks cannot be used. While there are many BPM implementation frameworks available at this moment, before implementing BPM the current situation (e.g. level of maturity) of the organization should be determined. If the company lacks the maturity on one of many critical success factors (Ravesteyn 2007) a BPM implementation could be delayed or even cancelled due to errors and lost in belief that it will ever work efficiently (Tregear, 2004). When a company intends to change its processes, ownership and design of the processes are interconnected. A company cannot change its processes with strong ownership and weak designs. The new design will probably be implemented at a fashionable speed and preciseness but the wrong changes would be made due to bad design of the processes. The same happens when a good design of the processes is made and no ownership or no power to change them is present. This means that they need to be at the same level of perfection, growth or development to be able to be changed efficiently (Hammer 2007; Rosemann & de Bruin 2004). To decide whether to implement the holistic BPM approach and to focus on which weaknesses the company currently has, the decision must be grounded on factors that are closely related to and cover the complete cycle of an implementation. A maturity model can help in determining at what maturity level the company is before the implementation starts. With each increase in maturity, new business opportunities become available per critical BPM implementation factor. When further maturing as an organization BPM Benefits such as improved benchmarks and the measurement of performance become available. When at the right maturity level they can be exploited with less risk and at a more fashionable rate, quality or speed. 9

10 However, current BPM Maturity models don t present the benefits, or rather opportunities that can be gained from climbing the maturity ladder with a focus on the opportunities, but on what is likely to be changed. The business value from implementing BPM, and in particular a BPMS is still residing in a grey area (Ravesteijn, 2009). BPM is an organizational change, meaning it will not just affect top management or the employee, but practically every stakeholder in a end to end process. Resistance to change is natural, so seeing the opportunities from either starting or continuing a BPM implementation is critical for the belief that is already scarce due to many failed ERP implementations (Bingi et al, 1999)(Hammer, 2007). By already having a list of opportunities that are common for a BPM implementation, the belief BPM can bring success can be increased. This list can then be mapped onto various maturity models, for instance the Business Process Maturity Model (BPMM) by the Object Management Group (OMG). The opportunities can for instance be allocated per maturity level for each factor. Also a general list of opportunities can be identified per factor used in a maturity model. When focusing on these factors more general opportunities can be identified. A clear framework containing opportunities gained from either climbing the maturity ladder or focusing on the general. The assumption is that opportunities that can be gained per factor of the maturity model itself will help getting that belief and thus the credibility needed for a BPM implementation. Most of the companies implementing (or wanting to implement) BPM are talking about the what and the why (Ravesteijn, 2007). After various research addressed the how (Ravesteijn, 2007;Ravesteijn, 2009;Tregear, 2005;Curtis, 2007; Hammer, 2007), this research addresses the why. 2.2 Objective and problem statement The objectives of this thesis project are; To identify the components a specific BPM opportunity consists of. To identify opportunities that can be gained by implementing BPM. To create a framework that presents the opportunities. Create a method to exploit the opportunities From the aforementioned objectives of this thesis project a problem statement can be derived as follows: How can organizations best identify BPM opportunities that (can) arise when a BPMS is implemented. To answer this research question a BPM Opportunity Model (BPMOM) will be developed. This model will make it possible to determine the current exploited opportunities and the preferred list of opportunities that can be exploited. A formal objective of the BPMOM itself is defined as: To create awareness of the various opportunities that can be exploited when implementing BPM and to determine which which opportunities can and should be exploited in order to gain more benefit from the BPM implementation. Furthermore by showing the benefits of these opportunities, changes that are necessary when implementing BPM are more easily accepted by the various (authority) levels of an organization (Black and Gregersen, 2003). 10

11 2.3 Research questions The following research question is proposed for this thesis project with the following sub questions: 1. How can an organization, relative to its maturity, assess the opportunities of a BPM implementation, such that. (criteria to identify when you are finished). a. What is Business Process Management (BPM) i. History ii. Definitions iii. Trends 1. Business Process Reengineering 2. Total Quality Management 3. Alignment 4. Maturity b. Which factors are important when considering the maturity of BPM of an organization c. How do IT and BPM relate to each other. i. BPM and SOA ii. BPM Suites d. What are opportunities in general and BPM Specific i. Which opportunities can be identified when implementing BPM 2.4 Research approach Two paradigm, or rather different concepts, are mainly present in the research of information science (Hevner et al, 2004). One is behavioral science, which predicts human or organizational behavior and grounds theories around this behavior. The second is design science where, often innovative, artifacts are created and with the help of these artifacts human and organizational capabilities are extended. A difference between the two concepts is the evidence. The outcome of behavioral science is based on theories with positive evidence, such as principles and laws. While there is still evidence needed for the justification of design science research, it is not based on principles and laws but on less tangible concepts as creativity, intuition and experience. Where behavioral science research tries to predict or explain behavior of the human being or organizational entity, design science research tries to extend the capabilities and exist as a problem solving paradigm. When explaining or predicting behavior, it is useful to propose an improvement or refinement strategy or best practice. While doing this it is also necessary to improve theories around the new design (Collins et al, 2004). Because the new design is based on grounded theory it adds to the (information) science literature. 11

12 Because the environment where design science is conducted is often based on learning and conducting new experiments, many variables cannot be controlled (Collins et al, 2004). The new design is therefore optimized as much as possible and the observations that are carried out must be as precise as possible. According to Collins et al (2004) these observations are of quantitative but also qualitative nature. Design science is often an iterative process because almost every aspect of the design is bound to be improved, incurring a new iteration. When applying the artifact in a business context an improvement cycle is started and the practical use is tested. A practical use of the new design is important, because without it is of same use as a new design that has a practical use but no grounding science theory to back it up (Hevner et al, 2004). For this research we propose the following general research objectives: 1. Create a solid knowledge foundation on the holistic field of Business Process Management (BPM). 2. Create an artifact that solves a problem of BPM in the field 3. Extend the current knowledge base on BPM in the field. While there are more objectives of design research, such as the improvement of an existing artifact, our main focus is to create a new artifact, namely the Business Process Opportunity Model. 2.5 Research strategy Hevner et al (2004) proposes seven guidelines when performing design research. While these guidelines are not to be followed exactly or in an sequential fashion, they are merely established to assist the researcher, editors, readers and reviewers to understand which are required when a design science research is to be performed effectively. Design an Artifact; Problem Relevance; Design Evaluation; Research Contributions; Research Rigor; Design as a Search Process; Communication of Research. While the artifact can have many forms (method, theory, construct, model) the properties of the artifacts are also important to take notion of. Often an artifact is created to be able to have a proofof concept (Hevner et al, 2004). An artifact is almost never intended to be a ready to implement tool. It can however evolve into a successful commercial product. An artifact mostly proves that it can be done. An artifact can also form the basis for a new design science research, or even a new iteration of such a research. The artifact should be purposeful, often to address an important organizational problem (Hevner et al, 2004). 12

13 The problem relevance refers to what the contribution is to the difference between the actual state of a system and the desired state, where a system could be an IT system or organizational system. Relevance is achieved when the problems faced are addressed, analyzed and/or described how to affect them (Hevner et al, 2004). The constraints and uses of design evaluation and the research contributions are already explained in the previous chapter, the evaluation methods are proposed in the next chapter, research instruments. The biggest and main contribution of this research will be a Situational Business Opportunity model. An extension of the current knowledge in the field of implementing BPM and assessing opportunities while implementing BPM will also be presented. The communication of this research will be through a master thesis and one or more papers which, hereby addressing to the last guideline of design science research: Communication of Research. 2.6 Research instruments At the start of this research an extensive literature study will be conducted to extend the knowledge on related topics as business process management, maturity, maturity models, alignment, situational method engineering and opportunities gained when implementing BPM. This study will help constructing a basic understanding of the holistic business process management methodology and the relations between the various concepts. While there are many available sources of evaluation methods for doing design science research (see table 1), the main research instruments used will be: Literature study, Case studies Surveys Observational Case Study Study artifact in depth in business environment Field Study Monitor use of artifact in multiple projects Analytical Static Analysis Examine structure of artifact for static qualities (e.g., complexity) Architecture Analysis Study fit of artifact into technical IS architecture Optimization Demonstrate inherent optimal properties of artifact or provide optimality bounds on artifact behavior Dynamic Analysis Study artifact in use for dynamic qualities (e.g., performance) Experimental Controlled Experiment Study artifact in controlled environment for qualities (e.g., usability) Simulation Execute artifact with artificial data Testing Functional (Black Box) Testing Execute artifact interfaces to discover failures and identify defects Structural (White Box) Testing Perform coverage testing of some metric (e.g., execution paths) in the artifact implementation Descriptive Informed Argument Use information from the knowledge base (e.g., relevant research) to build a convincing argument for the artifact s utilityfv Scenarios Construct detailed scenarios around the artifact to demonstrate its utility Table 1. Design evaluation methods (Hevner et al, 2004) 13

14 2.7 Scientific relevance Because of trends like globalization and commoditization (i.e. transformation from services and goods into commodities) there is a pull from the market to introduce methodologies like BPM. Also the push from the technology makes BPM easier to implement, for instance web services and the internet make it possible to communicate easier, safer and faster. The need for BPM is there, only after various failed ERP implementations (Bingi et al, 1999) credibility and belief in the success of a BPM Implementation must be present (Tregear 2005). To have the interest in BPM continue and not disappear for over a decade as has happened to workflow management (Aalst 2002a) a solid body of knowledge on BPM needs to be present. To date various BPM Maturity Models have been proposed (Object Management Group, 2008;Fisher, 2004; Hammer,2007; Rosemann & De Bruin, 2005) and various implementations methods as well (Aalst, 2002; Brahe & Bordbar, 2007; Rinderle, Kreher and Dadam 2005) but no models give a clear list or picture on what the opportunities actually are, gained from implementing BPM at various maturity stages. In fact, this is one of the very few scientific research performed on opportunities, let alone BPM opportunities. By replacing the core characteristics as for instance presented in Fisher s model by opportunities we hope to create another, perhaps better, type of (maturity) model, namely the BPM Opportunity model. The advantages of this new type of model are discussed in detail in this thesis. 2.8 Social relevance With every failed (BPM) implementation, belief in (change) methodologies disappears. Therefore it is important to be able to tackle problems that could arise during an implementation, preferably before the implementation takes place. To be able to tackle those problems effectively a body of knowledge (capabilities) and belief (credibility) must be present (Tregear, 2005). To gain belief and acceptance of change the beneficial opportunities must be ready to be presented. A clear list or picture of these opportunities is needed and helpful for managers or consultants that are trying to gather that belief. Also more research funded and empirically tested work could improve the professionalism of IT Business Consultants. 2.9 Challenges One of the challenges is to make the model as generic as possible. Every company has different cultures, policies and governance structure. All these factors are important when implementing BPM and some companies should have stronger focus on for instance change management than others. Another challenge will be the validation. Most of the factors on the BPMOM will have effect on different parts of the organization. This requires cooperation and commitment from every part of the organization to ensure the quality of the validation. On the other hand, this can be covered by interviewing (either personally or through a survey) people who are working with the different parts of an organization and experiencing all these difficulties. A result from choosing this strategy is however that another difficulty arises, namely the challenge to have these people cooperate with the validation. 14

16 3 Theoretical Background 3.1 Business Process Management The following chapter will elaborate on the first research question; What is Business Process Management? Often new concepts arise from either a push from the market, or a pull from technology. Sometimes both are present. The pull from technology is elaborately explained by Aalst (2003). In his paper he identified three trends that are relevant for BPM, namely: 1. From coding (e.g. IT systems) each line from scratch to gluing together complex pieces of software 2. From data to process driven approaches of information systems development 3. From design to re redesign of processes and applications. The following two paragraphs will elaborate on these three trends History The concept of software can be divided into four layers (Aalst, 2003). The first and inner layer is the operating system. The second consists of generic applications such as typing or spreadsheet applications that can be and is used in almost all organizations. The third layer consists of domainspecific applications which are specifically made for a domain, such as call center software. The 16 Figure 1 Trends in Information systems (Aalst et al, 2003)

17 fourth layer consists of tailor made applications, which have specific functionality for a specific task or process. The first trend can be identified by the fact that only the first and the fourth layer existed in the sixties. For every new bit of functionality new code had to be written. Today a lot of generic applications exist and the challenge is to glue the applications that reside on the fourth layer together. Not just the information systems engineers focused on a more process driven approach, also management changed its perspective on the company. The definition of BPM by Zairi et al (1995a) support the notion of the third identified trend. They see BPM as a structured approach to analyze and continually improve fundamental activities such as manufacturing, marketing, communications and other major elements of a company s operations Zairi et al (1995a). Looking at the BPM lifecycle and comparing it with the lifecycle of Workflow management, the change from design to re designing of processes and applications can also be seen. Process measurement and evaluation are done in order to receive feedback on the processes and to be able to create backup plans, such as an emergency response plan, but also perhaps more importantly discover trends and design flaws (Muehlen, 2005; Wetzstein et al, 2007) Hype Cycle According to the hype cycle of Jeston et al (2006), see figure 3, the first wave of BPM started with the creation of Six Sigma in 1986 (please see Appendix C for the emerging technologies hype cycles of 2007 and 2008). Figure 2 Hype Cycle explained Figure 3 Hype Cycle according to Jeston et al (2006) Many companies, for instance Sony, Chrysler, IBM and Pioneer were on the edge of bankruptcy or had giant losses during the nineties as they did not acknowledge the sensitivity processes need, not taking for instance organizational culture into mind (Keen, 1997). Because of many process engineering failures interest faded and interest did not return for another wave until the beginning of 2000 (Keen, 1997; Aalst 2002). Still, businesses are reliable on the BPM way of doing business (Smith & Fingar, 2003). Until around 2002 theories and systems were not able to cope with problems the real world presented. When the difference in business and IT thinking disappeared and the lag between management intent and execution was reduced. 17

18 The hype cycle of Jeston et al starts in 1986 with Six Sigma which is a bundle of proven quality principles and techniques that can be implemented on a highly effective manner. The methods that are proposed for six sigma have all been around (even back then) for several decades. The main aim was to reduce the amount of errors business processes caused. While traditionally companies have three of four sigma levels, Six Sigma, obviously, aimed for six levels, reducing the amount of errors by several thousand percent in response to the increased complexity of processes and increased expectations from customers (Pyzdek, 2001). The five tools used for Six Sigma, define, measure, analyze, improve and control look similar to the BPM lifecycle presently proposed. As Six Sigma gained more interest, Hammer received tremendous interest on his work with the title Don t Automate, Obliterate. The concept of process reengineering was getting more attention in combination with automation through IT. Hammer identified that the biggest problem of the nineties was that processes that were automated weren t changed accordingly. The only benefit gained was processes that went a hundred times faster, now also showed hundred times more or faster the errors. Also reengineering is not a small task and often encapsulates a change in the whole organization (Hammer, 1990). As can be seen from the hype cycle, during the late nineties, Business Process Reengineering (BPR) was proposed as the number one drivers of change for organizations. One of the reasons BPR hyped was because markets were getting more competitive but also more customer oriented (Motwani et al, 1995). According to Zairi (1995b) BPR was first introduced by Hammer, Davenport and Short in Radical performance improvements were claimed by these authors that were outlining a new approach of managing processes. The following definition on BPR was chosen out of the various literature, because it is elaborate and includes some (even though minor) benefits; to rethink, restructure and streamline the business structures, processes, methods of working, management systems and external relationships through which we create and deliver value (Talwar, 1993) One of the tools and techniques that are used, can today be found in just about any BPM suite or solution, namely process visualization (Zairi, 1995b). The difference however is that today s tools not only offer visualization but also simulation and almost a 1:1 enactment. This means that when the model is created in the design phase, none or little programming work has to be done in order to change the business process according to the process model Noel(2005). IT seems to be critical to BPM, often by implementing a BPM Suite/System. For BPR, IT was merely a powerful enabler, but not a necessary one. Furthermore change management, benchmarking, industrial engineering and process and customer focus are important and well mentioned aspects of BPR in literature (Zairi, 1995b) Definition When comparing the definitions on BPM a conclusion can be made that although the same term or concept name has been used, the body of knowledge on methods, techniques and models has changed. The following definition on a Workflow Management System is given by the Workflow Management Coalition (Lawrence, 1997). 18

19 A system that defines, creates and manages the execution of workflows through the use of software, running on one or more workflow engines, which is able to interpret the process definition, interact with workflow participants and, where required, invoke the use of Information Technology (IT) tools and applications. While the comparison with WFM is maybe a little bit off, a definition on BPM is therefore presented in the same year, a structured approach to analyze and continually improve fundamental activities such as manufacturing, marketing, communications and other major elements of a company s operation. (Zairi, 1997) A study done by Weske (2004) defines BPM as follows; Supporting business processes using methods, techniques, and software to design, enact, control, and analyze operational processes involving humans, organizations, applications, documents and other sources of information. This definition shows that BPM mainly has a supporting role for business processes. A comparison with one of the predecessors of BPM, Workflow Management, shows that there are several lessons learned. BPM is not just about automating and supporting processes with IT. It is about analyzing and often redesigning processes in order to increase efficiency, compliance and governance. A more recent definition given by Gartner further elaborates it is not only about IT or management but also about governance. "BPM is a management practice that provides for governance of a business's process environment toward the goal of improving agility and operational performance. BPM is a structured approach employing methods, policies, metrics, management practices and software tools to manage and continuously optimize an organization's activities and processes." Gartner (2006): The emphasis on the fact that BPM is a management practice is important. By managing BPM the company ensures, or at least tries in an optimal way, that resources are spent wisely on predefined goals. BPM affects the whole company and such a project requires (change) management. However the difference between the Gartner s 2006 and Weske s 2004 definition is the notion of governance. In a practical example governance makes sure the people who need to have work done, get it done and are rewarded for it. Also ensuring that the necessary qualifications and capabilities are present is a form of Business Process Governance (BPG) (Kirchmer). Governance as a whole has gained interest in the last five years, especially in the information system business (Richardson, 2006). The concept of governance, and process governance as a whole fits with the requirements of process reengineering, and thus BPM. The Gartner definition emphasizes on the continuous optimization of the orga nization s activities and processes. For this to happen effectively, assigned responsibilities per process are required. More on governance however will be presented in the IT Governance and BPM chapter. Furthermore one major trend can also be related to BPM just as BPR, namely Total Quality Management (TQM) (Ravensteyn, 2007;Chang, 2006) which is explained in the following chapter. 19

20 The history of BPM, which can be graphically presented by the hype cycle and the many definitions of BPM show that BPM is a very holistic topic involving many different fields of study. The following chapters will elaborate on the most closely related topics to BPM, such as TQM, WFM, BPR, BPMS, SOA, IT Governance and Alignment. 3.2 Total Quality Management Total Quality Management (TQM) emerged from the change from competitive positioning (think of Porter s five forces model) and industry structure to internal, firm specific management thinking, which occurred in the eighties (Cool & Schendel, 1988). The main goal however is external, namely Customer Satisfaction (Ross, 1993). Ross identified three trends that helped TQM to be accepted and applied in the scale it was (and still is): 1. The increasing domestic and global competition, especially from Japan (Powell, 1995) 2. The pervasive need to integrate the several organizational functions for improvement of total output of the organization. This also includes the quality of the output within each function. 3. The acceptance of TQM in various service industries. In the early nineties, 93% of America s largest 500 companies adopted TQM (Powell, 1996), which is astonishing and it supports trend number three identified by Ross (1993). While defining TQM is like shooting a moving target (Boaden, 1997), the second trend can be supported by the definition of TQM presented by Ross. The reason for the difficulty to define it according to Boaden is because it is a practice that spreads it wings over various aspects, which makes it difficult because other initiatives emerge and take it over partly. TQM is an integrated management philosophy and set of practices that emphasizes, among other things, continuous improvement, meeting customers' requirements, reducing rework, long range thinking, increased employee involvement and teamwork, process redesign, competitive benchmarking, team based problem solving, constant measurement of results, and closer relationships with suppliers. (Ross, 1993) The following key issues and terminology related to TQM are summarized by the Conference Board: 1. Cost of quality: the cost incurred because of not meeting customer requirements 2. Cultural change: An emphasis on the fact that employee s need to change in their behavior so that customers requirements, employee involvement and continuous improvement are addressed by management and all employee s. 3. Mechanisms of change: such as training, education, recognition (incentive programs), teamwork, communication and customer satisfaction programs 4. General TQM implementation tasks: define the mission, identify output and customers, negotiate customer requirements, 5. Management behavior: management acts as a role model, uses quality processes and tools, encourage communication, sponsor feedback. 20

21 Traditional measures implemented for control quality were made to have a shield against defects and process failures. Many steps and points for quality management were developed, such as Deming s 14 points for management, Juran s 10 steps for quality improvement or Crosby s 14 points for management.(ross, 1993). See Appendix E for a total list of these points of TQM. After carefully comparing the works of these pioneers and commercially successful writers, the following common themes can be identified (Ross, 1993): 1. Inspection is not a good method for quality improvement 2. A culture of commitment to quality are best achieved with the involvement of and leadership by top management 3. When starting a program for quality, organization wide effort, training and a long term commitment are essential 4. First quality, then the schedule. A study conducted by Powell in 1995 revealed that the key to better performance with TMQ lies more in the intangible aspects like culture, organizational skill and leadership. The following points of TQM were found correlating with better performance while using TQM; executive commitment, an open organization and employee empowerment. Later on, in 2005, Soltani (2005) conducted an extensive research on what was proposed the most important factor for TQM; top management involvement. The result was that it indeed was the most critical factor and that a dearth of evidence can be found to support this notion. Packard defines the role of the management as follows: the leader shows the need and sets the vision, defining the basic purpose, goals, and parameters or requirements of TQM (Packard, 2005) TQM & BPR A similarity between BPR and TQM is quickly found; the focus on processes. However, BPR is more radical in terms of change. While TQM tries to understand, plan and organize processes, BPR tries to redesign them. Other aspects are also identified as both used in TQM as in BPR, which are; benchmarking, culture change and performance management (Zairi, 1995b). Davenport (1993) proposes a healthy combination between BPR and TQM. While the former is radical, the latter is all embracing. According to Zairi (1995b) benchmarking, cultural changes and performance measurement are aspects identified for both TQM and BPR. Davenport (1993) identifies the notion of processes as necessary entities for BPR and TQM to be effective. Instead of just changing the organizational structure, behavioral change is necessary for truly effective changes. When the behavior is not changed accordingly change is often not sustainable. Time is therefore a necessary element for both practices. For TQM because continuous improvement requires cultural change ( people do not change overnight ) and BPR because often information systems are required to be built and that requires time as well. Davenport proposes a timeframe of approximately one or two years for changes to return any value. However differences are greater than similarities according to Davenport. The following were identified: Improvement programs are satisfied with a improvement rating of around 10%, while reengineering programs often opt for the tenfold of that. 21

22 Improvement programs start with the current flow, and innovation (or reengineering for that matter) start with a clean sheet Improvement programs base the improvement on statistical (operational) data, while the innovation programs tend to identify technological or organizational process factors that maximize variation and create fruitful changes Davenport explains why knowing the differences is important. When for instance the goal is to innovate the processes, but the employee s are only empowered to make small incremental improvements, employee s become confused and start tidying up the desk when the bulldozer awaits outside (Davenport, 1993). From this chapter we have mainly learned that TQM and BPM are related. More importantly from the identified literature we can derive several opportunities which eventually will be used in the BPM Opportunity model. 3.4 Maturity The next chapter will explain why alignment is important, what benefits can be gained from alignment and what the relation is between BPM and alignment. A preliminary conclusion can be drawn that alignment is important, however alignment can only be achieved by measuring the maturity on various components of the company. The following chapter will explain the history, give a definition and show how maturity is measured. Perhaps the most famous model when it comes down to maturity, is the Capability Maturity Model (CMM) (Herbsleb, 1997). In the nineties the CMM was used in approximately thousands of companies and resources spent on software process improvement rocketed into billions of dollars (Herbsleb, 1997). They contain the essential elements for effective processes (CMMI Product Team,2002). At the beginning there were several types of CMM s, with different purposes, for instance systems engineering and software engineering. Later on they were combined and proposed as the Capability Maturity Model Integration (CMMI). The focus of such a model is 1. to improve the processes of an organization (Constantinescu, 2007) by 2. providing guidance and best practices when developing processes (CMMI Product Team,2002). 3. Create or sustain the ability to manage maintenance, acquisition and development of products and services. The CMM and also the CMMI all work with a 5 tier maturity level. An amount of maturity levels proven to be used in a lot of other models created after the CMMI. A Maturity level can be defined as following: evolutionary levels toward achieving a mature software process (Van Vliet, 1993) These levels are necessary when a company wants to mature because every level of maturity needs a foundation for the next stage (M.GCMMI Product Team). Often to climb up a level of maturity, a number of actions need to be taken. Van Vliet (1993) calls these actions process areas (just as in the 22

23 CMMI by the M.GCMMI Product Team), each process area defines issues that have to be taken care of before one can mature to the next level. Later on in the chapter on Business Process Maturity Models we can see that these process areas are now used again. Hammer (2007) also gave a definition on maturity, whilst using it in his Process Audit paper on the process and enterprise maturity model. When becoming more mature, the company increases its potential to deliver high performance. Also using maturity levels is effective when trying to predict the current of maturity (M.GCMMI Product Team). The Object Management Group (OMG) presented in 2008 the Business Process Maturity Model (Object Management Group, 2008). With five maturity levels used in the model, an extensive explanation on the use and purpose of the maturity levels was given. The OMG uses maturity levels as plateau s for organizations to be able to step on to. Each plateau comprises of a set of goals that are to be achieved in order to be able to mature to the next stage. The following definition is given by the OMG group on maturity levels: A maturity level is a defined evolutionary plateau of process improvement A Maturity level is not to be confused with a capability level. Both have the same goal; increase organizational processes. However, while considering a maturity level each process area needs to be accounted for before attempting to mature to the next level. This is necessary because a foundation needs to be present for the next maturity level when maturing. Of course a level five maturity level process area can be instituted when the whole company is at a different level (e.g. level 3), but the company must understand that the risk of implementing this process area carries a high(er) risk of failure (M.GCMMI Product Team). A capability level is a different approach for incrementally improving processes. Maturing trough capability levels is achieved by addressing and improving single process areas. Maturing per maturity level is also called staged maturation. Figure 4. Meta model of the OMG BPMaturity model; staged vs specific maturation 23
